Elateriformia

Slime flux beetle Nosodendron unicolor, from here.


Belongs within: Polyphaga.
Contains: Dascillidae, Buprestidae, Byrrhoidea, Elateroidea.

The Elateriformia are a diverse group of beetles. Many elateriforms have a heterogeneous life cycle, with long-lived larvae ecologically disparate from the short-lived adults. Adults often have a streamlined body and complex pro-mesothoracic locking device. The antennae are rarely clubbed and often serrate, and the hind coxae are usually more or less excavate to receive the femora (Lawrence & Britton 1991).

Molecular phylogenetic analysis (McKenna et al. 2015) supports the inclusion in the Elateriformia of Nosodendron, a genus of ovoid, shining black beetles found as both larvae and adults feeding on slime fluxes in tree wounds. Nosodendron differs from other elateriforms in possessing a well-defined, three-segmented antennal club (Lawrence & Britton 1991). Unusual antennae also characterise the Rhipiceridae, which have pectinate antennae in the females but flabellate, many-segmented antennae in the males (Lawrence & Britton 1991). Otherwise, a close relationship between the Rhipiceridae and Dascillidae (together forming the Dascilloidea) is supported by features of the prothoracic interlocking device, wing venation and aedeagus (Lawrence & Britton 1991).
